Title: Improvements relating to the treatment of fabrics and articles made therefrom
Inventor: EVANS JOHN GWYNANT
IPC: D06M17/00
Filed: 1951-05-28
Abstract: 727,591. Shrinking fabrics; compound sheet materials. BRADFORD DYERS' ASSOCIATION, Ltd. May 22, 1952 [May 28, 1951; April 21, 1952], Nos. 12882/52 and 9965/53. Divided out of 727,569. Classes 42 (1) and 140. In a process for making a pre-shrunk multiply fabric or fabric article, the bonding together of the assembly of plies is at least initiated and the assembly is compressively shrunk in a single operation by the combined application of heat and pressure. For the bonding and shrinking, the plies may be passed through a continuous compressive shrinking machine of the type in which a rubber or other belt passes over two rollers and is engaged by a third roller which makes a nip with the first of the two rollers; the third roller is heated to a temperature between 110‹ and 200‹ C., according to the bonding material used, sufficient to bond the plies together during the shrinking operation. A continuous interliner may be fed between two outer plies to such a machine. If the multi-ply assembly requires heat on both sides, it may, on leaving the rubber belt, pass through a pair of rollers, the roller which is on the same side of the assembly as the belt being heated; or potentially adhesive bonding material may be pre-plasticized by plasticizing agents and/or by passing the assembly through a pre-heating zone. When forming a collar or other small article, the article may be passed through a continuous machine or may be treated on a machine such as that described in Specification 541,831, [Group VII]. The multi-ply assembly may comprise outer cotton fabric plies with an adhesive or potentially-adhesive interliner. The interliner may be (a) a fabric impregnated with an adhesive or potentially adhesive material in the form of powder or an aqueous dispersion, e.g. vinyl and acrylic resins or polythene, (b) a film of polythene or unvulcanized rubber, (c) a fabric including cellulose acetate threads which are made adhesive by immersion in a solvent or (d) a fabric made wholly or in part of thermoplastic material in fibre or filament form, e.g. vinyl resins, polythene or polyisobutylene. Alternatively, the assembly may consist of two fabric plies, one of which has been coated on its inner face with a dispersion of polyvinyl acetate and dibutyl phthalate in water to which sodium alginate has been added, and then dried ; the two plies are bonded together at 150‹ C. Specification 402,087 also is referred to. Reference has been directed by the Comptroller to Specification 545,770.

Filed: 1945-05-24
Abstract: 582,079. Mounting oil burners. CASSELDEN, A., and CARRERAS, Ltd. May 24, 1945, No. 13001. [Class 75 (i)] In a burner 1 in which means are provided for automatically turning on the oil supply when the burner is clamped into the holder and for cutting off the oil supply when the burner is removed, a pivoted shield 13 is linked to a lever 12 controlling the oil supply so as to move to cover the joint of the burner when the lever is moved to allow oil to flow to the burner, and to uncover the joint when the lever is moved to cut off oil from the burner. To secure it in its holder, the burner has a recess 7, Fig. 1, engaged by a spring-pressed button 6 on an arm 3- so that when a clamping screw 5 bearing on a boss 9 of the burner is advanced by rotation of a wheel 8, the button 6 is moved back against the action of its spring and a spring/loaded ball valve is moved off its seating so that the central bore of the burner communicates with the oil supply passage. When the lever 12 is moved to allow oil to flow to the burner, a cranked arm 17 moves a shield 15 to which it is attached to cover the clamping wheel 8 and allows a pivoted shield 13 to move under gravity to cover the burner point, an extension 19, Fig. 4, of the shield being held by the arm 17 to prevent the shield from being moved to uncover the joint. When the lever is moved to cut off the oil supply, the arm 17 rotates until it engages a lug 18 on the shield 13, when it lifts it to uncover the burner joint. The clamping wheel shield 15 may be provided with a similar lug and frontal extension to the shield 13 so that both shields are operated in same way by the arm 17.

Title: Homogenizing mechanism
IPC: B01F15/00
Filed: 1936-05-08
Abstract: 474,983. Centrifugal emulsifiers. JENNINGS, H. W. K. (Bowen Research Corporation) May 8, 1936, No. 13105. [Class 23] In an emulsifier where the material is driven centrifugally between baffles, the speed of the emulsifying rotor is controlled in accordance with the rate of feed of the material. A housing 19 secured to the cover plate 14 of the chamber 11 carries a bearing 21 in which the hollow shaft 15 rotates. This shaft is driven by a turbine wheel 23 supplied with pressure fluid from the pipe 25 through the valve 26 and the nozzle 24. The emulsifying rotor 30 is secured to the bottom of the shaft 15 and consists of parallel discs with radial blades 31 provided with forward and backward fins 32, 33 which act as baffles. As the material passed through slots in the hollow shaft is thrown outwards through the rotor, it is subjected to impact and shearing stresses by the fins. The emulsified material passes into the chamber 11 from which it is discharged when the valve 60 is opened. This valve 60 is connected by its stem 61 and link 63 to the device 62 which is connected by a pipe 64 to the chamber 11, and is responsive to the pressure in the chamber, so that the valve is opened when the emulsified material raises the pressure sufficiently. The valve 26 in the turbine supply pipe is controlled by means of a floating plate 35 journalled on the housing 19 and carrying a number of permanent magnets 37 in close proximity to a disc 38 rotating with the hollow shaft 15. The plate 35 tends to rotate with the disc 38 and a roller 40 on the top of the valve spindle is normally held against the plate by a spring 41. If the speed rises the plate is subjected to a greater torque and a cam 39 on its lower face depresses the valve to diminish the fluid supply. The material to be emulsified is fed through the pipe 53 and valve 54 to the tube 42 which is provided at its lower end with vanes 44 to start the material rotating before it enters the rotor 30. The vertical position of the vanes may be adjusted by the screw 48. A cavity 50 in the cap 49 above the tube 42 is joined by a pipe 58 to the pressure responsive device 56 which controls the valve 54. When the suction in the cavity 50 increases, owing for instance to increased speed of the rotor 30, the valve 54 is opened wider to increase the feed of material. A rotary measuring wheel 66, Fig. 6, may be arranged beneath the discharge outlet 59, and wells 68 closed at the bottom by hinged flaps 69. The wheel is driven by ratchet mechanism 72 actuated by the pressure responsive device which communicates with the interior of the chamber 11. In a modification the valve 54 in the feed pipe 53 is controlled in accordance with the speed of the rotor by the apparatus shown in Fig. 9. The disc 80 rotates with the rotor 30 and exerts a torque, against a spring 85, on a segmental plate 81 provided with permanent magnets 87. The valve is actuated by the segmental plate. This apparatus may also be used to control the entry of pressure fluid to the turbine.

Title: Storage battery active material
IPC: C23F11/12
Filed: 1955-05-06
Abstract: The active material of lead storage batteries consists of lead oxide with a minor proportion of an arylhydroxybenzoic acid which serves to retard oxidation of the formed negative plates.  The additive may consist of 0.1 to 5 per cent by weight of the material or a concentrate containing 50 per cent of arylhydroxybenzoic acid may be formed, to which lead oxide is added when required for use.  Suitable acids are 3 - phenyl - 2 - hydroxy, 4 - phenyl - 2 - hydroxy, 5 - phenyl - 2 - hydroxy, 2 - phenyl - 4 - hydroxy, and 2-phenyl - 3 - hydroxy benzoic acids. The lead oxide may be litharge with or without finely divided metallic lead, or red lead.  According to an example lead oxide containing 30 per cent finely divided lead and 0.7 per cent of 3 - phenyl - 2 - hydroxy benzoic acid was mixed with dilute sulphuric acid to form a paste which was pressed into grids and the resultant plates assembled in a battery.  The plates were electrochemically formed in an electrolyte of 1.010 specific gravity and after forming were removed, drained and dried; it is preferred not to wash the formed plates free from electrolyte. The formed plates may be air dried.  The active material may be modified by the addition of expander materials such as blanc fixe and carbon black.

Abstract: 1,132,162. Testing A. C. machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 7, 1967 [March 25, 1966], No.13416/66. Heading G1U. An apparatus for analysing the performance of an A.C. machine 1 incorporates two positional resolvers 6, 12 having three phase stators and two phase rotors the rotors being mechanically coupled to that of the test machine through gearing such that they are driven at relative speeds in the ratio of the relative numbers of poles on the respective machines. By means of tranformers 18, 19 connected across the windings of the test machine, voltages are developed across resistors 21, 22, which are fed to amplifiers 23, 24 whose gains may be adjusted so that currents proportional to the phase voltages of the test machine may be fed to the stator winding of the first resolver 6. Further, using current transformers 31, 32 and adjustable amplifiers 35, 36, currents proportional to the phase currents of the test machine are fed to the stator windings of the resolver 12. The voltages induced on the rotors of the resolvers which are driven in unison with the rotor of the test machine, represent the two axis component voltages and currents of the test machine respectively, and signals proportional to these are derived at 29, 30 and 41, 42 respectively. The desired voltages are compared with calculated valves to analyse the performance of the machine. The calculated valves are obtained from Park's transformation, as explained in the Specification.
